Honest question: Silver, why would you insist on trying to salvage a photo that simply went wrong? That turned out a blooper?

There is no way to salvage the second of these two photos.
A photo that went wrong in the process of its making cannot be saved, not by the bestest of post processing software.

Post processing only works with photos that are a good basis to work with from the start. They are not miracle programmes that repair just about everything.

You get the first close-up of the thistle. Which is fine as it is. Maybe the DOF is too shallow for some, maybe some find your composition is too tight on the flower, or its placement within the frame is not good ... all such points are debateable.

Why do you insist on salvaging the second?
Sorry for being so blunt, but the second is a photo for the bin.
